Long-term Follow-up of Hand-degloving Injury Treated by Conventional Methods.

Despite medical advances, degloving injury remains one of the most difficult traumatic injuries to treat. The conventional method for treating degloving injury of the hand is reconstruction with a groin flap. However, few reports have described the mid- or long-term functional and aesthetic outcomes after a hand reconstruction with a groin flap. This case report describes a 68-year-old woman with no specific medical history who presented with a severe degloving injury of the right hand, caused by a roller machine. The area of skin loss was covered with a pedicled groin flap that was separated after 3 weeks. Five years after the reconstruction, she had poor functional and aesthetic outcomes. The Japanese Society for Surgery of the Hand version of the Quick Disabilities of the Arm, Shoulder and Hand score was 57.5; the Hand20 score was 60; and the Michigan Hand Outcomes Questionnaire score was 37.5. The static two-point discrimination of the index and middle fingers was more than 15 mm, and Semmes-Weinstein monofilament examination showed that the sensation thresholds of these fingers were purple and blue. The range of motion was 10-degree angle of extension and 60-degree angle of flexion for the metacarpophalangeal joints of the index and middle fingers. Grip strength was 0.0 kg; pulp pinch strength of the index and middle fingers was 1.1 and 0.8 kg, respectively; and side pinch of the index and middle fingers was 0.1 and 0.7 kg, respectively.

Wide-Awake Approach for Flexor Digitorum Superficialis Tendon Transfer Followed by Early Active Mobilization.

Background The standard clinical practice to treat closed ruptures of the flexor digitorum profundus (FDP) tendons includes free tendon grafting; however, it is not suitable when the muscle amplitude of the ruptured FDP is not sufficient. We report outcomes of six patients who underwent flexor digitorum superficialis (FDS) tendon transfer of the ring finger using the wide-awake approach to repair the closed rupture of the FDP tendon of the little finger in zone 3 or 4. Methods The patients were identified by reviewing our institutional billing records from January 2012 to October 2019 for the International Classification of Disease 10 code M66.3 that describes the diagnosis as "spontaneous rupture of flexor tendons." Results The patients comprised two men and four women with an average age of 72.2 years (standard deviation [SD], 8.4 years). All patients were hospitalized after surgery to undergo early active mobilization. The average total active motion at the final evaluation was 201.8° (range: 85-248°). According to Strickland's criteria, outcomes were excellent for two, good for three, and poor for one patient. No patients complained about the ring finger. Conclusion These results suggest that FDS tendon transfer is recommended when the muscle amplitude of the ruptured FDP is insufficient. We believe that the wide-awake approach and early active mobilization may contribute to satisfactory outcomes.

Incidence of tenolysis and features of adhesions in the digital flexor tendons after multi-strand repair and early active motion.

We report seven patients requiring tenolysis after primary or delayed primary flexor tendon repair and early active mobilization out of 148 fingers of 132 consecutive patients with Zone 1 or 2 injuries from 1993 to 2017. Three fingers had Zone 2A, two Zone 2B, and two Zone 2C injuries. Two fingers underwent tenolysis at Week 4 or 6 after repair because of suspected repair rupture. The other five fingers had tenolysis 12 weeks after repair. Adhesions were moderately dense between the flexor digitorum superficialis and profundus tendons or with the pulleys. According to the Strickland and Tang criteria, the outcomes were excellent in one finger, good in four, fair in one, and poor in one. Fingers requiring tenolysis after early active motion were 5% of the 148 fingers so treated. Indications for tenolysis were to achieve a full range of active motion in the patients rated good or improvement of range of active motion of the patients rated poor or fair. Not all of our patients with poor or fair outcomes wanted to have tenolysis. Level of evidence: IV.

Predicting functional recovery and return to work after mutilating hand injuries: usefulness of Campbell's Hand Injury Severity Score.

PURPOSE: We investigated the effect of severity and form of mutilating hand injuries on functional recovery and return to work, and the usefulness of an injury-severity score in predicting these outcomes. METHODS: We reexamined patients in whom finger amputation or near amputation had been treated with replantation or revascularization at our institution at least 3 years earlier. We evaluated radiographs, sensory recovery, finger range of motion, skin temperature, and current overall hand function to calculate Tamai and Quick Disabilities of the Arm, Shoulder, and Hand scores, and recorded return-to-work status, duration of treatment, and time away from work. We determined injury level, number of involved fingers, type of injury, and Campbell's Hand Injury Severity score (HISS) from the medical record. RESULTS: The average age of the 50 enrolled patients was 43 years (range, 18-69 years); average follow-up was 7.8 years (range, 3.1-15.3 years). More proximal injuries, more involved fingers, and more complicated injury predicted poorer functional recovery. HISS was highly correlated with Tamai's score (r = -0.77; p<.001) and moderately correlated with the Quick Disabilities of the Arm, Shoulder, and Hand score (r = 0.39; p = .009). HISS was only moderately correlated with length of treatment (r = 0.32; p<.05) and with time away from work (r = 0.34; p<.05). Mean HISS among the 3 return-to-work groups differed remarkably. When HISS was <50, 11 of 12 patients returned to their original jobs; when it was between 50 and 150, 17 of 23 patients were able to return; and when it was >150, only 4 of 15 were able to return to work. CONCLUSIONS: Given the current surgical care of patients with mutilated hand injuries, HISS determined at the time of injury can adequately predict functional outcome and return to work status. Larger studies will be necessary to validate these findings.
